To all 4cham tt mayconoerm. y Be it known that we, ANDREW DICKEY. and

JOHN S. PERRY, ot' the'city and countyof Albany, and Sta-tev of New York, haveinven ted certain new andnseful Improvements in .Heating-Stoves; and Wedo hereby declare ,that

the following is afull, clear, and exact descrip- 1 tion thereof, reference being hadgtoQtheaccompanying drawings, making .part of this.

It will be observed thatthe grate or lirebed is placed in a plane below the base of the lfire-pot or combustion-chamber proper, thus forming the free open space R, for the increase of the draft for the protection of the grate or 'ire-bed, for facilitating the removal of clinkers and other refuse, for illuminating the draftchamber base-section, and for other purposes. The standards upon which the grate-trame rest can be made at any desired length, and thereby the depth of the free open space R regulated to the size of coal used in the stove. This grate or lire-bed `is placed about the center of the draft-chamber ba-se-section, and made with a diameter or area greater than the diameter or area ot' the inside of the said tirepot or combustion-chamber proper at its base. It is isolated from the walls ofthe said draftchamber.ibase-sectionl to allow a free circulation of air between the two, around and over the periphery of the said gratenpward to the burning fuel, and also to allow the passage of ashes and other refuse from the surface ofthe said grate or fire-bed downward into the ash pit.l f; i i. "The said space R' extends into the gas-combustionpchainber e, and with the latter forms a part of the said drat'tchamber base-section. The centralportion f ot' the said grate or tirebed is supported upon a tilting or dumping bar, h, and is kept in horizontal position by the stop and shaking lug i. It is pivoted to this bar h, as shown at h2, and can be vibrated lhorizontally and dumpedV vertically in the usual manner. v. The fire-pot B is suspended bythe flange b at the top upon the annular flange a, projecting from the inner side of the wall or case E. It is in the form of a inverted truncated cone, scalloped at its lower end, and extends down `toward the center of `thedraft-channber base section, terminating `a little distance above the top surface ot' the grate or fire-bed. The outer wall L L of the draft-chamber base section is ogee in form, and extends from the hollow base I to the top oi' the tire-pot or combustion-chamber proper. A considerable space, e e, is formed between the said wall and the fire-pot or combustion-chamber proper and the grate or iire-bed, for the purposes before described. Windows or doors Q, Q, for illumination, are placed in the said wall opposite or a little above the incandescent fuel which is exposed in the open free space It.

The opening Z is in the inner rear wall s, at a point between the top ofthe fire-pot or combustionchamber proper and the grate or firebed, and is provided' with a register-slide, `fn. This opening leads into the ascending ilue H, through which the air will be drawn away from the lire, thus checking the combustion, and when the grate is shaken the light ashes or dust will be borne 'upon this current into the said flue instead of dying out into the apartment. `When the slide n'. is closed, and the draft-register b3 opened, the tire will burn as usual. i

Between the lower part of the magazine() and the top b ot'V the tire-pot the two flue-passages j la are formed in the inside rear wall s, the latter of which is provided with a damper, m. Behind these passages vertical lines G H are constructed, so as to inclose these'passages. The ue G isformed with an arching hood, and it extends down to the hollow base I, and connects with the lues M and N formed in said base. The flue H also extends down to and connects with the same, and also extends up above `the said arching hood of the flue G to the exit-pipe H. Fig. 5 of the drawings illustrates the division of the chamber in the hollow base by the plate O, forming two `horizontal tlues, M N, which are connected together at p. By this arrangement of the tlues Gr H and M N a very smallv portion ofthe outer wall L L is covered, and thus, while a direct and indirect circulation of the products of combustion is secured throughout'the hollow base, illuminating windows or doors can be applied to the whole remaining wall L L. i i 1 This very desirable combination cannot be realized in revertible-ilue stoves of the ordinary description, in which the products of combustion are carried over the edges of the tire-pot or combustion-chamber proper, downL ward along its sides, and thence into the hollow base. l In thus constructing the said "ilues Gr H side by side, a less projection is required than i if they were placed one in front of the other, andthe beauty of the structure is further secured by embodying them withi'nthe external wall or main body. A further advantage is obtained in the material increase of the draft of the stove by this arrangement. A portion of the heat in passing down the ilue G is, by conduction, passed through the vertical plate s1 into the upward flue H, and the air in the same becomes thereby raretied, and thus a good draft is insured, the absence ot' which is a serious objection in most of the revertibleiue stoves constructed upon the old princi-ple.

The magazine C is suspended by means of lugs c c on projections d d, within the chamber formed by the outer case K, which may be cylindrical, or of any other desired form. This magazine is tapering at its lower end, and extends downward into the intermediate sections E, which also forms the upper mica section. The top of the magazine adjoins a funnel-shaped feed-hopper, F, above and within the same, which is closed by a top cover, F1. Gasescape passages F2 are provided from the top of the magazine into the tine s2 s2. This Hue extends all around the magazine, and is enlarged downward from the flanged, where the magazine begins to taper.

By this construction a large horizontal and lateral dame-expansion chamber for the burning of the gases is formed above the top of the fire-pot or combustion-chamber proper.

Operation: When the tire is to be started, the direct draft-passage k is to be opened, also register b3 under the grate. When the fuel has become ignited, close the former by the damper m, when the products of combustion will descend the iiue G into the hollow base I, pass forward in the ue Minto the lue N through the passage p, and thence upward through the ue H to exit-pipe H. The entire structure thus becomes thoroughly heated, including the `hollow base, and also the chamber s s,rwhich forms a drum, radiating the heat powerfully. The inflammable gases are burned in the combustion-chamber r r, producing', with the reflection from the incandescent fuel, a brilliant illumination through the windows P P.

When the grate or tire bed has become clogged with ashes, clinkers, and other refuse, this can be removed with a poker, scraping the same from the surface of the grate over its edge, from whence it will fall between the same and the walls of the draft-chamber base section into the ash-pit or ash-drawer. Shaking the grate or re bed should be avoided as much as possible, as this process packs the coal in a solid mass, and thereby impedes a free combustion. The check-passagel should be opened while the grate is being cleaned, as the draft into it will prevent any ashes or dust iiying into the room.

A brilliant illumination through the windows Q Q will reward a little attention to keeping the outer rim or enlarged portion of the grate or tire-bed free from refuse matter.

When it is desired to clean the hollow base, remove the cover t of same, when every portion can be easily reached, and the work ef- 'ectually performed.

We do not claim the device shown in patent of W. Keyser, December 27, 1870, of supporting the pan or ring upon which the grate or tire-bed rests, upon legs reaching to the base of the ash-pit section, as our plan is designed to permit of the use of an ash-pan for receiving ashes from the fire above. Another object we have in view is to have the ring and its supports of such a short length that it will be convenient to cast the two together, and when in use may be removed for repairs and replaced without taking the whole structure apart.

We claim- 1. rlhe combination of ascending and descending tlues placed on the rear side ofa stove, illuminating windows or doors in the draft-chamber base-section, and the free open space R, between the top surface of the grate or fire-bed andthe base of the tire-pot or combastion-chamber proper. f

2. The combination of ascending and descending tlues placed in the rear of a stove, a free open space between the top of the grate and lowell end of the tire-pot sufficiently large to permitthe removal of clinkers and other obstructions, illuminating 'windows opposite said space, and a grate or tire-bed having an open space between it and the walls of the stove to admit of clinkers and other obstructions being dropped between the grate and said walls of the stove'into the ash-pit, substantially as described.

3. The combination of the check-draft passage l, having a damper, n, to open and close the same, with the upward ilue H and the ash-pit, substantially as-described.

4. The grateframe constructed with legs, supported upon, and in combination with, a ange or .projection upon the side wall of the draft-chamber base-section, substantially as described. Y
